Doom 3	Source: id Software

Doom 3 takes advantage of the latest videocard technology and pushes the processing power of the CPU to its absolute limit. At its highest setting, Ultra quality, texture sizes pass the 500MB mark which means even tomorrow's videocards will have a hard time running everything. The frame rates in the game itself are locked at 60 fps so anything above that point is wasted. Each test is run three times with the third run being recorded.

These benchmarks are starting to look like a broken record... All socket AM2 Athlon64 motherboards perform about the same, when identical processors are involved. It's important to note that SLI is a high end feature not generally noticable at lower gaming resolutions.

Quake 4	Source: id Software

Quake 4 is the latest shooter from ID and is based on the Doom 3 engine. Tweaked to for more eye candy, Quake 4 promises to be tougher on videocards and systems than its predecessor was. Quake 4 also does not have a 60 fps limiter like Doom 3, with the Ultra setting, graphic textures can surpass the 500MB mark! Each test is run three times and with the third run being recorded.

Quake 4 numbers for the EP-MF570 SLI are identical to what we saw with Doom 3. It's not surprising since both games are based on the same 3D engine. The Epox EP-MF570 SLI is no slouch at 3D games just because it is based on nVidia nforce 570 SLI chipset as opposed to a nForce 590 SLI.

Next up, we answer that age old question - is the Epox EP-MF570 SLI motherboard worth the drive to the computer store?
